Pressure-Volume State - Heat & Thermodynamics Step by Step

A gas state can be described by pressure, volume, and absolute temperature.

highlighted = computed this step

Read pressure and volume

This gas state has pressure 2 pascals and volume 6 cubic meters.

p = 2\ \text{Pa}\qquad V = 6\ \text{m}^{3}

Pressure times volume has units of energy in this unit system.

pV = 2\ \text{Pa}\cdot 6\ \text{m}^{3}

Multiplying 2 by 6 gives 12 joules.

pV = 12\ \text{J}
